To deliver the best VoIP product, we have a selection of approved hardware and VoIP requirements that work together to continue to improve your Masiero Voice experience.
Technical Aspect Requirements
- Disable SIP ALG.
- This is the most important and critical setting to change.
- This is also known as SIP Transformations.
- Ensure the router/firewall does not block the phones' NAT Binding/Keep-Alive packets that are sent every 15 seconds.
- Most routers do not block the phones' Keep-Alive packets by default, but may on high-end firewalls.
- Some firewalls do not have an option to allow the packets, so an alternate solution is to set the phone's UDP session timeout to 300 seconds, since the phones send a SIP packet re-registration request every 5 minutes.
- Ensure that internet traffic is not blocked on ports: 5060 or 5062
Request your Internet Service Provider create a Port-forwarding rule to allow internet traffic inbound/outbound on port 5060. - The phones and other Masiero Voice devices must be behind a NAT-enabled firewall and must get their private IP addresses via DHCP or Statically assigned.
- Allow WAN pings from our Call Quality Monitoring Servers.
- This is needed for call quality monitoring and troubleshooting purposes.
- This is needed for call quality monitoring and troubleshooting purposes.
- Ample amount of bandwidth to allow for stable connectivity and communication.
